Comparison and Analysis of Different Software Cost Estimation Methods
Sweta Kumari,Shashank Pushkar
International Journal of Advanced Computer Sciences and Applications , 2013,
Abstract: Software cost estimation is the process of predicting the effort required to develop a software system. The basic input for the software cost estimation is coding size and set of cost drivers,the output is Effort in terms of Person-Months (PM’s). Here, the use of support vector regression (SVR) has been proposed for the estimation of software project effort. We have used the COCOMO dataset and our results are compared to Intermediate COCOMO as well as to MOPSO model results for this dataset. It has been observed from the simulation that SVR outperforms other estimating techniques. This paper provides a comparative study on support vector regression (SVR), Intermediate COCOMO and Multiple Objective Particle Swarm Optimization (MOPSO) model for estimation of software project effort.We have analyzed in terms of accuracy and Error rate. Here, data mining tool Weka is used for simulation

International Journal of Caring Sciences , 2013,
Abstract: The current investigation was focused at documentation, analysis and interpretation of ethnomedicinal phyto wisdom in Hamirpur District of Himachal Pradesh. The impoverished tribal and rural people of Hamirpur District (Himachal Pradesh, India) do not receive satisfactory primary healthcare. They have crudely been stillexploiting traditionally the medicinal plants existing in their surrounding environment for diverse purposes including ethnomedicine use. The objective of the study was to document ethnobotanical knowledge primarily of notable herbs employed by the different backward people, whether tribal or rural, in the area under study.Ethnomedicinal data was accessed through structural interviews, and discussions with the tribal/rural informants, healers, medicine-men/women, etc. (with age between 45-65). Minimum five to eight informants were taken into consideration for each claim. This investigation brought on record that people of the study area(Hamirpur) generally utilize about 50 plants species belonging several distinct families. Different plant parts such as leaves, flowers, fruit, stem-bark and root are most commonly employed. A fair wide range of diseases are treated by people of Hamirpur district using local medicinal plants. These ethnomedicinal claims may aid in finding novel phytoconstituents for welfare of mankind. The data would be useful for further scientific exploration.

Existence of Equilibrium Points in the R3BP with Variable Mass When the Smaller Primary is an Oblate Spheroid  [PDF]
M. R. Hassan, Sweta Kumari, Md. Aminul Hassan
International Journal of Astronomy and Astrophysics (IJAA) , 2017, DOI: 10.4236/ijaa.2017.72005
Abstract: The paper deals with the existence of equilibrium points in the restricted three-body problem when the smaller primary is an oblate spheroid and the infinitesimal body is of variable mass. Following the method of small parameters; the co-ordinates of collinear equilibrium points have been calculated, whereas the co-ordinates of triangular equilibrium points are established by classical method. On studying the surface of zero-velocity curves, it is found that the mass reduction factor has very minor effect on the location of the equilibrium points; whereas the oblateness parameter of the smaller primary has a significant role on the existence of equilibrium points.
Genome-Wide Expression of Transcriptomes and Their Co-Expression Pattern in Subtropical Maize (Zea mays L.) under Waterlogging Stress

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0070433
Abstract: Waterlogging causes extensive damage to maize crops in tropical and subtropical regions. The identification of tolerance genes and their interactions at the molecular level will be helpful to engineer tolerant genotypes. A whole-genome transcriptome assay revealed the specific role of genes in response to waterlogging stress in susceptible and tolerant genotypes. Genes involved in the synthesis of ethylene and auxin, cell wall metabolism, activation of G-proteins and formation of aerenchyma and adventitious roots, were upregulated in the tolerant genotype. Many transcription factors, particularly ERFs, MYB, HSPs, MAPK, and LOB-domain protein were involved in regulation of these traits. Genes responsible for scavenging of ROS generated under stress were expressed along with those involved in carbohydrate metabolism. The physical locations of 21 genes expressed in the tolerant genotype were found to correspond with the marker intervals of known QTLs responsible for development of adaptive traits. Among the candidate genes, most showed synteny with genes of sorghum and foxtail millet. Co-expression analysis of 528 microarray samples including 16 samples from the present study generated seven functional modules each in the two genotypes, with differing characteristics. In the tolerant genotype, stress genes were co-expressed along with peroxidase and fermentation pathway genes.
Student Dropout Risk Assessment in Undergraduate Course at Residential University
Sweta Rai
Computer Science , 2014,
Abstract: Student dropout prediction is an indispensable for numerous intelligent systems to measure the education system and success rate of any university as well as throughout the university in the world. Therefore, it becomes essential to develop efficient methods for prediction of the students at risk of dropping out, enabling the adoption of proactive process to minimize the situation. Thus, this research work propose a prototype machine learning tool which can automatically recognize whether the student will continue their study or drop their study using classification technique based on decision tree and extract hidden information from large data about what factors are responsible for dropout student. Further the contribution of factors responsible for dropout risk was studied using discriminant analysis and to extract interesting correlations, frequent patterns, associations or casual structures among significant datasets, Association rule mining was applied. In this study, the descriptive statistics analysis was carried out to measure the quality of data using SPSS 20.0 statistical software and application of decision tree and association rule were carried out by using WEKA data mining tool.
Relative Equilibria of a Satellite Moving in an Elliptic Orbit Subjected to Gravitational and Aerodynamic Torques  [PDF]
Kumari Ranjana
International Journal of Astronomy and Astrophysics (IJAA) , 2014, DOI: 10.4236/ijaa.2014.41019
Abstract: Here we consider the attitude motion of a satellite, subjected to gravitational and aerodynamic torques in an elliptic orbit. The determination of orientation of equilibrium points has been discussed. It is found that they coincide with those for the circular case as studied by Sarychev and others in the works [1]-[3] and besides we have aimed at the sufficient condition for stability in the sense of Lyapunov.
User Informatics Optimized Search and Retrieval-Congestion Avoidance Scheme for 4G Networks  [PDF]
Pushpa Pushpa, Sweta Sneha, Rajeev Agrawal
Communications and Network (CN) , 2012, DOI: 10.4236/cn.2012.43026
Abstract: The objective of 4G network is to provide best services to the users which in turn made the performance of existing network more critical. Further, the large traffic generated in such networks creates congestion resulting in overloading of the system. Frequent delays, loss of packets, and in addition the number of retransmission/paging also increases the computational cost of the system. This paper proposes a novel way to reduce overloading and retrieval mechanism for VLR through optimized search, based on the information of users mobility pattern (User profiles based (UPB)) to track the user. This not only improves the overall performance of the system, especially in the events when the visitor location register (VLR) is overloaded due to heavy traffic and congestion of the network. It was also established through simulation studies that the proposed UPB scheme optimizes the search and reduces the average waiting time in a queue. In addition, the provision of VLRW (waiting visitor location register) avoids the overloading of main VLR and provides a recovery/retrieval mechanism for VLR failure.

Sweta Sengupta, James Arocho, T. Christopher Windham
Journal of Cancer Therapy (JCT) , 2013, DOI: 10.4236/jct.2013.42068
Abstract:

Introduction: The rate of squamous cell carcinoma spontaneous regression (SR) remains unknown because incidences are rare and underreported. Case Report: We present a case of a 92-year-old Caucasian female who was found to have a 1 cm lesion on her nose. Pathologic evaluation supported the diagnosis of a moderately-differentiated squamous cell carcinoma. The patient refused treatment and returned with no clinical evidence of disease several months later. The lesion spontaneously regressed without excision. Discussion: Frequency of SR of malignancies has been estimated to occur 1 in 80,000 to 100,000 cases [1]. The biologic mechanisms of SR in malignancies remain unclear. Further investigations into the mechanisms of SR may identify potential treatment strategies for cancer.

An Overview of Various Security Aspects for WiMAX Network Technology
Manorma Kaushik,Sweta Kaushik
International Journal of Electronics and Computer Science Engineering , 2012,
Abstract: WiMAX, Worldwide Interoperability for Microwave Access, is an emerging wireless communication system that provides broadband access with large-scale coverage. As a cost-effective solution, multihop communication is becoming more and more important to WiMAX systems. To deploy successfully multihop WiMAX networks, security is one of the major challenges that must be addressed. Another important aspect is how to support different services and applications in WiMAX networks. New ICT and e-Learning strategies and advances in Wireless standards and technologies particularly in the areas of WiMAX (Worldwide Interoperability for Microwave Access) and mobile computing can help to make the digital divide in education and research fields. This technology aim to provide low-cost, high-performance wireless access to residential and business applications. The required features and performance of the system will increase as technology evolves to address portable and mobile applications. Our study can provide a guideline to the WiMAX for the design of a more secure and practical network.
